Subject: [PATCH 0/9] spi: Use dma_request_chan() instead dma_request_slave_channel()

Hi,

dma_request_slave_channel() is a wrapper on top of dma_request_chan()
eating up the error code.

With dma_request_chan() drivers can receive the real error code and can support
deferred probing against DMA.

The series has been compile tested only (allyesconfig).

Regards,
Peter
